This patch updates the corresponding glibc bits/mman.h headers accordingly, and updates the Linux kernel version number in tst-mman-consts.py to reflect that these constants are now current with that kernel version. Tested with build-many-glibcs.py. 2019-09-24 Joseph Myers * sysdeps/unix/sysv/linux/powerpc/bits/mman.h [__USE_MISC] (MAP_SYNC): New macro. * sysdeps/unix/sysv/linux/sparc/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. * sysdeps/unix/sysv/linux/tst-mman-consts.py (main): Update Linux kernel version number to 5.3. diff --git a/sysdeps/unix/sysv/linux/powerpc/bits/mman.h b/sysdeps/unix/sysv/linux/powerpc/bits/mman.h index 198600e34b..db850f1ea4 100644 --- a/sysdeps/unix/sysv/linux/powerpc/bits/mman.h +++ b/sysdeps/unix/sysv/linux/powerpc/bits/mman.h @@ -36,6 +36,8 @@ # define MAP_NONBLOCK 0x10000 /* Do not block on IO. */ # define MAP_STACK 0x20000 /* Allocation is for a stack. */ # define MAP_HUGETLB 0x40000 /* Create huge page mapping. */ +# define MAP_SYNC 0x80000 /* Perform synchronous page + faults for the mapping. */ # define MAP_FIXED_NOREPLACE 0x100000 /* MAP_FIXED but do not unmap underlying mapping. */ #endif diff --git a/sysdeps/unix/sysv/linux/sparc/bits/mman.h b/sysdeps/unix/sysv/linux/sparc/bits/mman.h index 732289bd4e..9eb83dcf3f 100644 --- a/sysdeps/unix/sysv/linux/sparc/bits/mman.h +++ b/sysdeps/unix/sysv/linux/sparc/bits/mman.h @@ -36,6 +36,8 @@ # define MAP_NONBLOCK 0x10000 /* Do not block on IO. */ # define MAP_STACK 0x20000 /* Allocation is for a stack. */ # define MAP_HUGETLB 0x40000 /* Create huge page mapping. */ +# define MAP_SYNC 0x80000 /* Perform synchronous page + faults for the mapping. */ # define MAP_FIXED_NOREPLACE 0x100000 /* MAP_FIXED but do not unmap underlying mapping. */ #endif diff --git a/sysdeps/unix/sysv/linux/tst-mman-consts.py b/sysdeps/unix/sysv/linux/tst-mman-consts.py index ea88888405..c11e2ea4ac 100644 --- a/sysdeps/unix/sysv/linux/tst-mman-consts.py +++ b/sysdeps/unix/sysv/linux/tst-mman-consts.py @@ -41,7 +41,7 @@ def main(): help='C compiler (including options) to use') args = parser.parse_args() linux_version_headers = linux_kernel_version(args.cc) - linux_version_glibc = (5, 2) + linux_version_glibc = (5, 3) sys.exit(glibcextract.compare_macro_consts( '#define _GNU_SOURCE 1\n' '#include \n',
